Acid Breath

Undines whose outsider heritage can be traced to a water mephit can wield acid as a weapon. Such an undine has a breath weapon that is a 5-foot cone of acidic water usable once per day. The breath deals 1d8 points of acid damage per two character levels (maximum 5d8). A Ref lex saving throw (DC 10 + 1/2 the undine’s level + the undine’s Constitution modifier)

halves the damage. This racial trait replaces the spell-like ability racial trait.
